Angelina Jolie sat for a four-hour interview with the FBI on October 18 regarding a reported incident with Brad Pitt on a private plane, US Weeklyclaims in a new report.

The Maleficent actress “fully cooperated” with the two FBI agents who visited her Los Angeles rental home to discuss an alleged physical altercation that TMZ says took place between Pitt and his son Maddox back in September, just days before Jolie filed for divorce. Several of Jolie’s six children were also questioned by the FBI.

“The agents wanted a breakdown of everything that happened from when the plane took off to when it landed,” a source told the publication. “They’re looking into charges of assault."

The Los Angeles County Department of Children and Family Services is also looking into abuse allegations, reports US Weekly, though Pitt has repeatedly denied any rumors of misconduct. As per the continued investigation, the DCFS has indefinitely extended their temporary settlement, which granted Jolie physical custody of the couple’s six children. That settlement was originally intended to expire on October 20.

“Neither side wants this to go to court because everything the FBI and DCFS investigated will potentially be made available to the public,” the source continued, “which would be bad for the entire family.”

The unnamed source also claims other potential witnesses — like the plane’s crew — were interviewed about the alleged incident. Once the agents complete their interviews, "they will bring the case to the prosecutor, who will evaluate whether they feel the need to bring charges against Brad. It could ­potentially be months.”

Jolie -- who first began dating the Benjamin Button actor in 2004 -- filed for divorce from Pitt on September 20 after two years of marriage. She released a statement via her lawyer Robert Offer that said, “This decision was made for the health of the family. She will not be commenting, and asks that the family be given its privacy at this time.”
